How to Refit a Live Environment Without Driving Its Occupants Mad!

Refit in a live environment

Making alterations to an existing building can come with a whole load of challenges. It’s often much more difficult than building from the ground up. The structure can constrain your design, and you will have to overcome any problems with it. That can be a lot tougher if the building has occupants who don’t want to vacate.

We come across this all the time, especially when refitting shops or offices. I asked Iconic’s Director of Project Management, Darren Hewitt, for his top tips to ensure a smooth build in a live environment.

Q: Why would anyone want to work through a building project?

Darren: It’s easy to see why a business would not want to vacate their premises, even when undergoing a significant refurbishment. For a retailer, closing a shop for even a short time will lead to a loss of revenue and may well result in customers deserting them for a competitor.

Barclays had these concerns when I worked as Construction Manager for the refit and refresh of their estate of Retail branches. They were determined to avoid closing the doors, at all costs!

Vacating an office is just as problematic, as alternative premises have to be found - adding significantly to the project budget and causing major disruption to the company and its employees.

Q: What are the main challenges for the Build Team?

Darren: The challenges are all about disruption. They include dirt, noise, vibration, access, logistics, deliveries of materials, removal of waste and hours of work.

Hours of work can be a particularly tricky one. Leases generally specify that the occupants have the right of ‘quiet enjoyment’. They may specify hours during which disruption is not allowed, perhaps 8am-8pm. However, many councils have constraints for construction work, restricting working hours to 8am-6pm Monday to Friday, or 8am–1pm on a Saturday. When this happens, your lease obligations conflict with local by-laws.

Q: How do you avoid disruption?

Darren: The reality is that you can’t altogether avoid it when working on a construction project. It would be unreasonable to expect the contractors to work without causing any disruption at all. I like to approach the project from a position of tolerance and reason – reminding everyone that they need to be tolerant and reasonable! That is easier said than done though, because people tend to get grumpy when they get disrupted. The answer is to listen to everyone’s perspective and find the middle ground. Mediation becomes the number one skill of the project manager.

Q: Have you worked in any live environments? How did you manage the disruption?

Darren: Yes. We acted as the project managers for the Live Office Refurbishment at the European headquarters of a Global Technology Giant at King’s Cross, London. Once the design stage concluded, the core challenge was managing the logistics of implementing the fit-out without moving 320 employees out of the building.

We deployed several strict strategies to protect the day-to-day business while the heavy works were carried out:

Dust and Vibration Control: To minimise dirt and vibration, we carpeted all the walkways throughout the building, as carpet naturally traps dust and deadens impact noise. We also utilised Tacky Mats at transition zones to stop dirt from tracking into operational office areas—a neat, inexpensive solution that made a massive difference.

Acoustic Management: Because building risers act as natural conduits for cabling and pipework, they also allow sound to travel between floors. To control the noise, we blocked all the risers with a temporary acoustic treatment, whilst strictly adhering to the building’s fire strategy.

Strategic Night Working: We were able to leverage the building’s location on a semi-estate, where council constraints on working hours were less restrictive. This allowed the contractors to carry out the most disruptive works during the night so that the client's business could carry on relatively uninterrupted during the day. While night working increased procurement costs, it was a highly worthwhile investment to safeguard the live business.

Q: Many of our clients have to keep their businesses running while a major refit is underway. How do you manage a complex construction project inside a live operational environment without bringing down their daily productivity?

Darren: This is where client-side advisory frameworks and meticulous project planning really prove their value. Managing construction inside a live operational environment requires an entirely different level of logistics. When a client's business must remain 100% functional, maintaining business continuity isn't just a preference—it’s a strict contractual requirement.

To keep daily operations completely unaffected, we build our project logistics around three non-negotiable rules:

Phased Segregation & Sound Management: We strategically map out construction schedules to isolate high-impact noise and dust. Heavy drilling, structural modifications, and material deliveries are strictly relegated to out-of-hours shifts, while temporary, floor-to-ceiling acoustic partitioning keeps active team spaces clean and quiet during daytime operations.

Absolute Business Continuity Mapping: Before a single tool is lifted, we audit all critical building infrastructure. We map out data servers, power grids, HVAC systems, and water mains to guarantee they stay entirely online. If a service interruption is absolutely necessary to tie in new services, it is meticulously planned for a weekend window with redundant backups in place.

Strict Health & Safety Segregation: A live construction site and an active corporate office cannot mix. We establish entirely separate access routes, designated contractor hoists, and independent delivery schedules. This ensures that tradespeople and construction materials move through the building completely isolated from your clients, employees, and public-facing areas.

Q: What is your top tip?

Darren: Keep communicating! That's the key to every project, large or small. If everyone feels their views have been heard and considered, they are much more likely to be tolerant and reasonable.

Thanks Darren!
